SELVAGE rnorrnoron.

Application filed May 22,

This invention appertainsto looms and more particularly to a novel device for connection with a conventional loomfor preventing the drawing-in of the cloth at the selvage and for forming a perfectselvage.

The primary object of this invention is to provide a needle arranged on each side of the, selvage and associated with the loom adjacent to the fell of the cloth and operable from the lay beam for engaging the filling or weft threads for preventing the drawing in of these threads and for allowing the correct passage of the warp threads during the forming of the cloth. i

It has heretofore been contemplated of prov viding aneedle or fork for. engaging the filling loops, but such devices have fallen short of their purpose and as far as I have been able to ascertain such devices have not been commercially successful, due primarily to the fact that in actual practice a certain variation exists in the forming of the loops and such devices have not considered this variation.

It is therefore a salient feature ofthis invention to provide a needle movable in a horizontal plane toward and away from the warp threads and the fell of the cloth and normally in position for receiving the weft thread Or filling during the formation of the loop and the travel of the shuttle through the shed, the filling moving the needle toward the fell and the needle thereafter'holding the loop in proper position during the beat of the reed.

A further object of the invention is the provision of novel means for operating the needle in a vertical plane by the lay beam when the reed pushes the filling thread in place, said means giving a smooth working steady action. eliminating the possibility of breakage and undue wear. Y

A further object of the'invention is to provide a needle for engaging the filling loops at the selvage for forming a perfect selvage'in which possible damage to the reed is elimi v nated either by the needle or the temple, with which the same can be associated.

Arfurther, object of the invention is toprovide a device for maintaining all warp ends and selvage ends parallel while weaving and which will give more loom width for weaving with the same reed space.

A still further object of the invention is to provide a novelloom attachment of the above character, which will be durable and efficient I in use, one that will be simple and easy to ordinary temple,

manufacture and which can be applied to a conventional temple and loom at a small cost.

With these and other objectsin view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a fragmentary topplan view of a conventional loom with the improved de- FICE.

vice applied thereto 'andconnected with an Figure 2 is a transverse section taken on the line 2-2 of Figure 1 looking in the direction of the arrows showing an end elevation of the improved attachment in its operative position for releasing the filling loop, the

needle having been raised by the lay beam,

Figure 4 is an e d elevation of the attachment n 1ts normal position,

Figure 5s a front elevation of the attach- I connected with an ment showing the same ordinary temple, h Flgure 6 is an end elevation of the attach} ment looking in the opposite direction from Figure 4. i

Referring in detail to the drawings 10 designates the breast beam, 11 the temple bar,

. 12 the lay beam and 13 the reed of a loom of well known constructiom, B designates one of the temples of the loom, and O my improved attachment or selvage protector, it be-. a

ing understood that the loom is provided with ,two temples and that each temple has assoc ated therewith one of the attachments. The I warp threads are indicated by the reference character 14, while the weft threads or filling is indicated by the reference character 15, The temple piece can be of any preferred character or type well known to the trade and has not been shown in detail. As illustrated the same includes the usual toothed roll 16 for engaging the cloth mounted within the housing 17, one end of which is provided with clamping means 18 for engaging a bracket 19 adjustably mounted on the temple bar 11.

In the present instance the novel device G is connected with the outerend of the temple preferably by means of the, clamping bolt 20 which extends through the clamping ear of the temple. c v

' temple and the leg 26 at the outer end of the supporting frame or body forms means for supporting the loop engaging needle 23 and the operating means 29 therefor.

The needle'28 includes an arcuate shank I port-ion 30 having at its inner end the depending inwardly directed loop engaging point 31. The opposite end of the arcuate shank 30 is provided with a substantially iii-shaped attaching portion 32, the outer leg of which is rockably mounted in the outer endof a swinging arm 33, whichforms a part of the operating means 29. As shown the extreme outer end of the arm 331s provided with a stop 34;

arranged in the path of the U-shaped attaching portion 32 of the needle 28, which forms means for limiting the outward swinging movement of the needle. The needle is nor mally held in contact with the stop by the use of a spring 35 coiled about the needle and having one end thereof attached to the arm and its opposite end attached directly to the needle. The inner end of the swinging arm 33 is connected to the outer leg 26 of the frame 25 by means of a suitable pivot 36 and the arm directly below the pivot is provided with an inwardly directed arcuate extension 37, the purpose of which will be hereinafter more fully described. It is to be noted that the arm 33 swings in a vertical plane and carries the needle therewith and that the needle itself is allowed a lateral swinging motion toward and away from the fell of the cloth as clearly shown in Figure 3 of the drawings and which will be hereinafter more specifically described.

An operating cam 38 for actuating the arm 33 is provided and-this cam includes a'rearwardly extending arcuate shoe 39 for a purpose, which will be also hereinafter more fully described. The cam at its inner end is mounted upon a suitable pivot a0 carried by the outer arm 26 of the supporting fr: me 25 and the cam above the pivot 40 is provided with a reai-wardly extending head 41 of a substantially circular formation for fitting in the extension 37, so as to allow the head 41 to act on said extension as well as against the lower edge of the arm The lower edge of the extension 37 is provided with a V- shaped notch 37 for engaging a shoulder e8 on the cam 33 when the arm 33 is raised for limiting the swinging movement thereof.

The shoe 39 on the cam operating lever 38 extends a suitable distance beyond the arm 33 and acts as a weight for normally holding the needle in a lowered position as shown in Figure 4 of the drawings. The arm and needle due to the formation and association thereof with the frame also have a tendency to be normally held in a lowered position and in the path of the weft thread or filling when the shuttle goes through the shed.

In operation 0L he improved device, the

same is attached to the outer end of the temples as described and the loom is operated in the ordinary manner. The hooked end 31 of the needle will engage the weft thread as the shuttle goes through the shed and the needle will be swung onits vertical pivot in a horizontal plane toward-the fell of the cloth holding the weft thread in place and effectively preventing the drawing in of the selvage thus making a perfect edge which is desirable on steamer rugs, auto robes, and the like.

The loop is held in proper position until the forward beat of the lay beam and reed, when the reed pushes the filling or Weft thread in place at which time the lay beam will come in contact with the shoe 39 and the shoe will ride on the upper face of the lay beam and raise the arm 33 in a vertical plane in a smooth steady action moving the needle 31. from out of the loop. Upon the return movement of the lay beam and reed the needle and'the shoe will at once assume their normal positions, for engaging the threadon the next stroke of the shuttle. If desired a long nar row fiber strip can be attached to the front of the lay to protect the faceplate from any wear by the lifting shoe.

Particular attention isinvited to the novel manner of mounting the needle 28 uponv the lifting arm 33 as the swinging movement of the needle obviates any variation in the formation of the selvage.

Changes in details may be made without departing from the spirit or scope of this invention, but:
